ENGINE-TRUCK.

T 0 all whom it may concern Beit known that I, CARL HOLMBLADE, a citizenof the United States, residing at Graceville, in the county of Bigstoneand State of Minnesota, have invented certain new and usefulImprovements in Engine Trucks; and 1 do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled iii the ai't to which it appertains to make andilse the same.

Thisiiiveiition relates to a truck or cart adapted to be connected tothe frame of a grain harvester and binder of any approved constructionfor the purpose of supporting an internal combustion'engine and itscooling tank independently of the ground wheels of the grain harvesterand binder, thereby enabling the machine to be used to better advantageon soft ground. i

This invention consists in the novel eoiistruction aiid combination ofthe parts forniiiig the truck or cart and as hereinafter fully describedand claimed.

In the drawings, Figure 1 is a side view of truck constructed accordingto this iiiveiition. Fig. 2 is a plan View of the same. Fig. 3 is an endview of a portion of the truck showing the connection of an adjustableframe section with the main frame.

The grain harvester and binder, or otherl similar agriculturalimplement, is of any approved construction, and 2 is a portion of itsframe which is provided with lugs 3 for theattachment of the truck. Thetruck has a main frame 4 the front end portion ory dra-ft bar 5 of whichis pivoted in the lugs 3, but the truck maybe pivoted to thefranie 2 inany other convenient way. "A

The main frame l is formed iii any approved way, and it has verticaluprights (l at its rear end which are connected together and to itsvarious frame members by any suitable braces 7 which will make a rigidstructure.

The internal combustion engine, indicated by dotted lilies 10, is placedon the rear part of the main frame 4, which form's a supporting platformfor it.

The internal combustion engine is operatively connected with themechanism of the grain harvester iii any convenient way which willpei-init the main frame 4 to move pivotally. ln the arrangement shown,the engine is connected to a couiitcishaft 12 by sprocket wheels 14 anda drive chain 15, and

Application filed January 18, 1916. Serial No. 72,782.

the countershaft 12 is journaled in bearings 16 on the frame 4f. Thecountershaft 12 has a telescopic extension 17 and universal joints orcouplings 1S for connectingit with one of the shafts of the harvester,and these parts afford the necessary flexibility of connection.

The main frame 4 is supported by ground wheels 20 which are journaled'on spindles 21 which project from adjustable pivoted f ames 22. Theframes 22 have vertical members 24 which are pivoted iii bearings 25which project laterally from the vertical upriglits 6 of tlie mainframe.

The axle spindles 21 are arranged to the reai' of the pivot members 24,and arms 26. project forwardly of said members. A coupling-rod 27extends crosswise of the truck and is pivoted to the arms 26 by pins 2S.The lower bearings 25 rest on collars 30 which are adjustable upon thevertical pivot members 24, and which are provided with Aset-screws 31,or similar fas'tenings, for se-` curing tlieiii in place. These collars30 are set so that the engine platform is horizontal, and. so that thecounterslia-ft 12 can be coupled up to the mechanism of the liarvesterto the best advantage.

An auxiliary frame 32 is provided -aiid is secured to the tops-of theupriglits (i, and is held rigid by suitable braces. A cooling tank 33 issupported by the frame 32, and v this frame is arranged above the levelof the of the harvester, and to turn around with it,

and the auxiliary frame or platform 32 is arranged above the level ofthe ground wheels so that they can turn under it.

That I claim is:

1. A truck comprising a main platform having a draft connection at `itsfront end and-vertical posts at its rear end, axle fiaiiies providedwith laterally projecting spindles and pivoted to theI said verticalposts so as to rock in a horizontal plane,

ground wheels mounted on the said spindles and projecting rearwardlybeyond the end and above the top of the said main platform, and anauxiliary platform arranged substantially parallel to the said mainplatform and supported by the said vertical posts above the said wheelsand to the rear of the said main platform and having its front portionbraced to the front portion of the main platform.

spindles and having vertical pivot members, bearings projecting from thesaid uprights and engaging with the pivot members, ad j ustable collarsfor supporting the said bearings on the pivot members, ground Wheelsmounted on the axle spindles, and an auxiliary frame secured'to theupper parts of the said uprights above the ground Wheels.

1n testimony whereof I have affixed my signature.

CARL HOLMBLADE.
